The shape of diamond segments is an important factor influencing the performance of diamond saw blades. The different shapes are directly related to cutting efficiency and the ratio of the diamonds’ non-normal failure.

Currently, there are many kinds of shape diamond segments, for example, convex segments, layered sandwich concave segments, L-shape segments, step-shape segments, segmented segments and side-slotted segments.

Various Shapes of Diamond Segments

The designing for the shape and structure of diamond segments mainly has two purposes. The first is to increase the diamond blade’s capabilities of containing and discharging sawdust, and improve the cooling and lubricating conditions. The second is to reduce the friction between the segments and the material being cut as well as the sawdust, improve the blade’s cutting capability, and thus save energy and improve the blade’s performance.

As there are slots on the rim of diamond blades, the length of diamond segments also influences the blade’ performance. In sawing, the diamonds on the front of the segment, which enter the cutting arc earlier, bear more loads than the diamonds on the back of the segment. Therefore we can segment the diamond segments properly, so that the performance of the front end and the back end of a diamond segment matches the loads they bear.
